Technically, DOS doesn't support those features. The program running on DOS can though. eg sound chips during the DOS days. Each game had its own audio driver for each chip. No OS support whatsoever. Looking back, it was rather insane: instead of programming to a standard audio interface provided by an OS, each game had to deal not only with its own audio interface, but drive the audio hardware directly. The same could be said for video, although video was quite a bit easier to deal with.
Totally agree. DOS was really a pretty funny world. It was back in the day when PCs were far more homogeneous. It really wasn't until windows 95/NT that things started to become way more sane. Though it is pretty horrifying to think that we ran in a world where ring 0 access was combined with internet access.
